This chemical is primarily used in the synthesis of pharmaceutical compounds, particularly in the development of chiral drugs. Its structure, featuring both amino and hydroxyl groups, makes it a valuable intermediate in the production of beta-blockers and other cardiovascular medications. The (S)-enantiomer is especially significant due to its role in creating optically active compounds with specific therapeutic effects. Additionally, it is employed in organic synthesis to introduce chiral centers into molecules, enhancing their biological activity and selectivity. Its application extends to the preparation of peptides and peptidomimetics, where it serves as a protecting group for amino functionalities during complex reactions.
